Abstract

The present invention relates to a vacuum cleaner with preseparation structure. Said vacuum cleaner includes vacuum cleaner main body, and is characterized by that in the interior of shell body of said main body are successively set a motor, a fan and a filter from gas inlet. A disk supporting seat is used for supporting said fan in the interior of said shell body, the internal space of said shell body is divided into two portions in the transverse direction, one end where the meter is mounted is air-intake channel, and one end where the filter is mounted is duct-collecting chamber, the left and right two sides of the described supporting seat are equipped with air inlet respetively, on the air inlet a non-return valve is set respectively.

Description

Technical field: [0001] The present invention relates to a vacuum cleaner, and more particularly to the structural features of the main body of the vacuum cleaner. Background technique: [0002] Existing household vacuum cleaners are all filtering vacuum cleaners, which can be divided into three types according to their shapes: vertical, horizontal, and portable. Its main structure is also composed of three major parts: dust collection chamber, filter, and fan arranged in sequence. Garbage and dust enter the dust collection part with the air, and are filtered by the filter first, then are detained in the dust collection chamber, and the gas is filtered again. After the device, it is discharged through the exhaust port. Since the inlet and outlet of the dust collection chamber are in the same direction, that is, the inlet and outlet of the dust collection chamber are "straight through", even though the volume of the dust collection chamber is large, it cannot achieve separat...
